Definitions

  • FIG. 11 is a block diagram illustrating one preferred example of the configuration of the pixel-specific characterization data calculation section 32 which performs the processes at steps S 12 and S 13 .
  • the pixel-specific characterization data calculation section 32 includes a filtered characterization data calculation circuit 36 , a filtered characterization data memory 37 and a pixel-specific characterization data calculation circuit 38 .
  • the filtered characterization data calculation circuit 36 calculates filtered characterization data D CHR _ FILTER associated with the respective vertices from the area characterization data D CHR _ AREA received from the area characterization data memory 35 in the area characterization data calculation section 31 .
  • the filtered characterization data D CHR _ FILTER includes APL data and variance data.
  • the approximate gamma correction units 22 R, 22 G and 22 B of the approximate gamma correction circuit 22 respectively perform correction calculations on input image data D IN R , D IN G and D IN B associated with each pixel 9 on the basis of the correction point data sets CP_sel R , CP_sel G and CP_sel B , respectively, which are calculated by the correction point data calculation section 29 , to thereby generate the output image data D OUT R , D OUT G and D OUT B (at step S 17 ).
